Set Size File Text on Matlab

Hi everyone, I have program that load text file using uigetfile :
[filepesan lokasi] = uigetfile({'*.txt'},'Browse file message');
this is capacity for file if text file is bigger than capacity
kapasitas=get(handles.txt_nkapaembed,'String');
kapa=str2num(kapasitas);
and codes for get text file size is
txtpesan = strcat(lokasi,filepesan);
infofile=dir(txtpesan);
file=infofile.bytes;
set(handles.txt_nukurfile,'String',num2str(file));
if (file >= kapa)
msg=strcat(num2str(kapa),{' bytes only will embed});
msgbox(msg,'warning','warn');
return
end
but in my algorithm program is that when text file is bigger than "kapasitas" size (ex. 100Kb), the text file should be "crop" until length of 100Kb.
how can I do that? need your advice, many thanks

if (file >= kapa)
maxfilesize = 100*1024;
else
maxfilesize = inf;
end
set(handles.txt_lokasipesan, 'String', txtpesan);
fid = fopen(txtpesan, 'r');
buffer = fread(fid, maxfilesize, '*char');
fclose(fid);
bacapesan = regexp( buffer, '\n', 'split');
set(handles.edt_pesanembedd,'String',bacapesan);

Your existing code,
bacapesan=textread(txtpesan,'%s','delimiter','\n','bufsize', 3000000);
resulted in bacapesan being a cell array of strings, so your code should already be expecting that. How did you handle it before now?
